86 GN I've had the car for 25 years with only driving it occasionally , just flipped 65 k miles. An aftermarket fuel pump was put in back in the day, but don't remember the specifics . Kenne Belle ram air intake and it may have been a Red Armstrong Chip. That was all done 25 years ago...

Thanks for your advice. It would act up some on 93 with 18 psi, but nothing like it is now at 21. I will retard the boost to where it was before the intercooler upgrade. I also thought it may be fuel pressure as I do not have a hot wire kit. I'm just getting started. I have a methanol...

Just added a duttweiler necked intercooler and picked up several pounds of boost in the process, but now the car pops and backfires ? What went wrong ? Boost has increased to about 21 psi, do I need to back it down some ? or look elsewhere for the problem ?
